Abstract

We present preliminary differential fiducial cross sections on Central Exclusive Production (CEP, pppXppp\to pXp) of two opposite-charge mesons (X=π+πX=\pi^{+}\pi^{-}, K+KK^{+}K^{-}) in midrapidity region with small squared four-momentum transferred from forward protons, 0.03<t1,t2<0.2 GeV20.03<|t_{1}|,|t_{2}|<0.2~\textrm{GeV}^{2}. The process was measured in the STAR experiment at the Relativistic Heavy Ion Collider (RHIC) in proton-proton collisions at the center-of-mass energy s = 200 GeV\sqrt{s}~=~200~\textrm{GeV}.
